Adverrun Contra System with 85MM spinner


Adverrun is a F3A drive developed to minimize the effects incurred by the rotating propeller.

Forces which affect the flight path of the plane are reduced in order to focus the pilots attention on performing the maneuvers.

Adverrun uses a combined Belt/Gear reduction gear to drive two Propellers rotating in opposite directions.

It has specially been build for F3A use by active F3A pilots with attention on the details.

The new Adverun XS was significantly reduced in weight compared to the 2016 model. It continous to be largly maintenance free.

Adverrun is offered in combination with a Kontronik Pyro motor.

It ships pre-assembled including motor and spinner and comes with screws and rubber mounts.

All alloy parts are anodized in Kontronik red. To match your planes spinner diameter size you can choose from a choice of 82mm and 85mm spinner.


Adverrun has been desgined for 10s Lipo packs. We have tested the most common propeller combinations.

  • Front: 22x20 / Rear: 22x22 (recommended)
  • Front: 22x20 / Rear: 22x20
  • Front: 20x20 / Rear: 20.5x20.5
  • Front: 22x18 / Rear: 22x20 (can be used - but we found it a bit too slow)
  • Front: 23x20 / Rear: 23x22 (can be used - but current concumption is quite high)

These combinations will yield in maximum currents of 90-120A on the ground providing more power than needed in a typical F3A flight.

Good to know that there is the little extra power for storms though ;-)

Weight has always been a concern in F3A and one of the reasons for the three year development phase till we were satisfied.

Weight depends on the used motor type. It is common to state weight of model drives without accessories.

We list weight w/o accessories for comparision with other drives, but also including spinner and accessories (i.e. screws and rubber mounts). Compared to other drives Adverrun also limits the need for using additional CFK mounting plates to fit the drive in your plane.
